specific Embodiment approach 1

[0012] Specific implementation mode one: combine figure 1 Describe this embodiment. This embodiment includes a first water well 1, a first-stage cyclone desander 2, two second-stage filters 3, a second water well 5, and a water source heat pump heat exchange mechanism 6. The first water well 1 passes through The pipeline is connected to the first-stage cyclone desander 2, and after the two second-stage filters 3 are connected in parallel, one end is connected to the output end of the first-stage cyclone desander 2 through the pipeline, and the other end is connected to the water source through the pipeline The input end of the heat pump heat exchange mechanism 6 is connected, and the water source heat pump heat exchange mechanism 6 is connected with the second water well 5 through a pipeline. Water source heat pump heat exchange mechanism 6 is composed of water source heat pump heat exchanger 6-1, heat exchanger 6-2, compressor 6-3 and throttling mechanism 6-4, water source he...

specific Embodiment approach 2

[0013] Specific implementation mode two: combination figure 1 This embodiment is described. The difference between this embodiment and the first embodiment is that it also adds an air collecting tank 4, which is arranged on the pipeline between the second stage filter 3 and the water source heat pump heat exchange mechanism 6. The air collecting tank 4 can discharge the collected air to prevent air bubbles from clogging. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0014] Specific implementation mode three: combination figure 1 This embodiment is described. The difference between this embodiment and the specific embodiment is that it also has two headers 10, and one header 10 is arranged in the pipe between the first water well 1 and the first-stage cyclone desander 2. On the road, a header 10 is arranged on the pipeline between the water source heat pump heat exchange mechanism 6 and the second water well 5 . This design is convenient for the conversion of the first water well 1 and the second water well 5 . Other components and connections are the same as those in the second embodiment.

Abstract

An underground water recharge well anti-jamming system, the invention relates to an underground water recharge well device and aims at solving the problems that once the recharge well is jammed the recharged water quantity into a single well becomes less and less and the water even cannot recharged; the well pipe filtering device is arranged underground and then the cleaning and maintaining are inconvenient as these works obstruct the application of underground water-supply heat pumps. A first well (1) of the invention is connected through pipelines with a first-class cyclone desander (2), two second-class filters (3) are connected in parallel, then one end is connected through the pipeline with the first-class cyclone desander (2) and the other end is connected through pipeline with a water-supply heat pump heat-exchanging mechanism (6) which is connected with pipeline with a second well (5). With the first-class cyclone desander and the second-class filters of the invention, the suspension substances in the first well can be filtered to prevent thin sands, etc. suspension substances from jamming the second well and to avoid the problem that the recharged water quantity into the single well becomes less and less and the water even cannot recharged, so as to lead the underground water-supply heat pump to be applied well.

Description

technical field [0001] The invention relates to a groundwater recharging well device. Background technique [0002] Groundwater source heat pumps have been used in engineering practice for more than 60 years, and the failure of recharge wells has often been exposed during these 60 years. Groundwater recharge often occurs when the recharge well is blocked. The blockage of the recharge well causes the water volume of a single well to be filled less and less, or even not filled, which hinders the application of ground water source heat pumps. [0003] The purpose of groundwater source heat pump recharge: [0004] (1) Protect groundwater resources and avoid geological disasters. Based on the serious shortage of groundwater resources and the current situation of long-term overexploitation, if there is a problem with the recharge technology of the groundwater source heat pump, and 100% of the well water cannot be recharged into the aquifer, it will make the current unoptimistic ...
